Letters Pa'tmt No. 101,672, dated April 5, 1870.

IMPROVEMENT IN TEAPOTS.

The Schedule referred to in these Letters Patent and making part of the same.

To all persons to whom these presents shall come:

Be it known that I, THOMAS SMITH, J r., of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improve-- ments in Tea and Coffee-pots, 860.; and that the following is a full and exact description of the same, reference being had to the accompanying plate of drawof bearing a high' degree of heatwithout injury, by attaching such sheettin or iron directly to and over the outside surface of the ordinary Britannia bottom,

through soldering or otherwise, and thus making said,

sheet-tin or iron-the contact surface with the stove, in combination with providing said sheet-iron or tin plate with one or more holes through its thickness, so

that in case of any leak to the pot between the Brit-- annia and tin-bottom plates, the steam generated between themcan have free exit and escape.

In the accompanying plate of drawings my improvements in tea and coti'ee-pots are illustrated.

Figure 1 being a partial side elevation of a teapot constructed according thereto, but with the bottom plates in transverse vertical section.

Figure 2 is a plan view of the bottom.

Figure 3, a detail view hereinafter referred to.

A in the drawing represents a teapot made of Britannia metal, of which I B is the handle;

Othe lid; and

D, the spout.

E is the bottom plate of teapot A, which plate is made of Britannia metal, spun up into any suitable shape or form.

F,a plate or sheet of tin or iron applied to the Britannia bottom plate E, upon the outside surface thereof, forming a covering to the same, where it is secured by soldering it along and around its edge a to the Britannia plate.

With a sheet-tin or iron bottom plate applied to the ordinary Britannia bottom of a Britannia tea or coffee-pot, as has been hereinabove described, the Britannia bottom and pot itself will not melt at a low degree of heat, but is rendered susceptible of resisting as great a degree as if made of sheet-tin or iron, or of a metal equivalent thereto, the advantages of which are obvious.

b, an aperture made in the center of the sheet-tin bottom plate B, through which, should there be any leak through the Britannia bottom of the pot, the steam that would consequently become generated in and between the two bottom plates can escape and pass off, thus avoiding all possibility of an explosion, which would be liable to occur were the steam allowed to be confined therein and no escape for it provided.

- ,In lieu of onev aperture 1) more may be provided, but one is deemed snflicient; and, furthermore, in lieu of the mode described and shown, in which the sheettinor iron bottom plate is applied to the Britannia bottom, it may be attached in the manner shown in fig. 3, or in various other modes as may be deemed best to serve the purposes of its use.

The sheet-tin bottom F may lie in direct contact with .the Britannia bottom E in lieu of, as shown in the drawings, with a space between.

Having thus described my invention, I shall statemy claim as follows:

The aperture 11 in bottom plate .11, substantially as and for the purpose described.

The above specification of my improvements in tea and cofiee-pots, 850., signed by me this 29th day of October, A. D. 1869.
